Characterization of flowing dispersions
First Claim
1. A microelectrical resistance tomography system comprising a sensor including a wafer substrate of electrically insulating material having an aperture bounding a fluid flow path through a tube and more than two sensor electrodes on the substrate disposed circumferentially around the aperture so as to contact fluid in the flow path and connected to a cable connector on the substrate, flow means to flow a fluid under investigation through the tube past the sensor, and electrical control and measurement means for applying selectively oscillating current to the sensor electrodes and measuring electric potentials across the sensor electrodes.
